The NFL is reviewing an elbow thrown by the Lions’ Ndamukong Suh to the head of Arizona’s Eric Winston in the Cardinals’ Week 2 win, ProFootballTalk.com reported Sunday night.

However, the site said, Suh is unlikely to be suspended for his actions, because the Lions have now played another game since then—Sunday’s win in Washington—while the play only came to its attention Saturday night.

Apparently, the Cardinals did not send video of the play to the NFL for review, the usual procedure for starting a review. However, a league source told ProFootballTalk.com that what Suh did was a clear violation of the rules.

Suh could still be disciplined for the elbow, however. He already has been fined $100,000 for a Week 1 illegal block on Minnesota’s John Sullivan during an interception return.
